Leviticus 14:12-18

14:12 “The priest is to take one male lamb and present it for a guilt offering along with the log of olive oil and present them as a wave offering before the Lord. 14:13 He must then slaughter the male lamb in the place where the sin offering and the burnt offering are slaughtered, in the sanctuary, because, like the sin offering, the guilt offering belongs to the priest; it is most holy. 14:14 Then the priest is to take some of the blood of the guilt offering and put it on the right earlobe of the one being cleansed, on the thumb of his right hand, and on the big toe of his right foot. 14:15 The priest will then take some of the log of olive oil and pour it into his own left hand. 14:16 Then the priest is to dip his right forefinger into the olive oil that is in his left hand, and sprinkle some of the olive oil with his finger seven times before the Lord. 14:17 The priest will then put some of the rest of the olive oil that is in his hand on the right earlobe of the one being cleansed, on the thumb of his right hand, and on the big toe of his right foot, on the blood of the guilt offering, 14:18 and the remainder of the olive oil that is in his hand the priest is to put on the head of the one being cleansed. So the priest is to make atonement for him before the Lord.
